CAAAC GHG Permit
September 14, 2012 - This final report (PDF) (152pp, 6.9 MB) presents potential GHG permit streamlining options and observations developed by the Clean Air Act Advisory Committee (CAAAC): Permits, New Source Review and Toxics Subcommittee GHG Permit Streamlining Workgroup. In April 2012, the EPA convened what we call the GHG Permit Streamlining Workgroup to explore potential streamlining approaches that may make the administration of the CAA permitting programs more efficient for permitting authorities, and that may potentially reduce the permitting burden for smaller GHG-emitting sources if the programs are expanded to apply to these sources.
Greenhouse gas (GHG) emissions from the largest stationary sources will, for the first time, be covered by the Prevention of Significant Deterioration (PSD) and title V Operating Permit Programs beginning January 2, 2011. These permitting programs, required under the Clean Air Act, are proven tools for protecting air quality and the same tools will be used to reduce GHG emissions. But the thresholds established in the Act for determining when emissions of pollutants make a source subject to these permitting programs, 100 and 250 tons per year, were based on traditional pollutants and were not designed to be applied to GHGs.
EPA’s GHG Tailoring Rule, issued in May 2010, established a common sense approach to permitting GHG emissions under PSD and Title V. The rule set initial emission thresholds - known as Steps 1 and 2 of the Tailoring Rule - for PSD and Title V permitting based on carbon dioxide equivalent (CO2e) emissions. EPA’s Step 3 of the GHG Tailoring Rule, issued on June 29, 2012, continues to focus GHG permitting on the largest emitters by retaining the permitting thresholds that were established in Steps 1 and 2. In addition, the Step 3 rule improves the usefulness of plantwide applicability limitations (PALs) by allowing GHG PALs to be established on CO2e emissions, in addition to the already available mass emissions PALs, and to use the CO2e-based applicability thresholds for GHGs provided in the "subject to regulation" definition in setting the PAL on a CO2e basis. The rule also revises the PAL regulations to allow a source that emits or has the potential to emit at least 100,000 tons per year of CO2e, but that has minor source emissions of all other regulated NSR pollutants, to apply for a GHG PAL while still maintaining its minor source status.
State and local permitting authorities have long-standing experience working together with owners and operators of industrial facilities, and EPA believes they are best suited to issue Clean Air Act permits to sources of GHG emissions. EPA is working closely with permitting authorities to ensure that the transition to GHG permitting runs seamlessly.

EPA comment letters on GHG permitting actions - This page contains EPA written comments on permit applications and draft permits that involve GHG emissions.
Permitting Guidance for GHG – EPA’s “PSD and Title V Permitting Guidance for Greenhouse Gases” provides the basic information that permit writers and applicants need to address GHG emissions in permits.
- PSD and Title V Permitting Guidance for Greenhouse Gases (PDF) (96pp, 11.2 MB) - March 2011 update (reformatted)
The document posted above incorporates updates to the guidance originally posted in November 2010. We provided an opportunity for comment, inviting comment on all aspects of the guidance, but most immediately requesting comments on technical errors. This updated March 2011 version of the guidance reflects the technical corrections that were identified during our review of those comments. We also received substantive comments on several broader policy issues. We will respond to those substantive comments as appropriate as we continue to implement the PSD program for GHG through issuing permits and responding to inquiries from stakeholders.
The following slides summarize the "PSD and Title V Permitting Guidance for Greenhouse Gases" and are for informational purposes only. EPA presented these slides during the stakeholder webinars on November 18 and 19, 2010. For more specifics on EPA's guidance on the permitting of GHGs, please consult the actual guidance document.

Interim Permitting Guidance for GHG Emissions from Bioenergy Production (PDF) (35pp, 622k) – This document provides guidance that permitting authorities may use when determining Best Available Control Technology (BACT) for GHG emissions at Bioenergy facilities. This guidance can be used on an interim basis as EPA completes its detailed examination of the science and technical issues associated with the accounting for biogenic CO2 emissions from stationary sources.
GHG Control Measures White Papers –This series of technical “white papers” summarize readily available information on control techniques and measures to reduce GHG emissions from specific industrial sectors. These papers provide basic technical information which may be useful in a BACT analysis, but they do not define BACT for each sector. The industrial sectors covered include:

Enhancements to the Control Technology Clearinghouse (known as the RACT/BACT/LAER Clearinghouse, or the RBLC) – This website provides access to information and decisions about pollution control measures required by air pollution emission permits issued for GHG by permitting agencies. Information is accessible to all permitting agencies working on similar projects. The expanded RBLC includes GHG control and test data, and a GHG message board for permitting authorities.
For more information on the enhancements to the RACT/BACT/LAER Clearinghouse, please contact Iliam Rosario at 919-541-5308, or email@example.com.
GHG Permitting Action Team – This team will assist permitting authorities respond to GHG permitting questions. The GHG Permitting Action Team, comprised of experienced senior staff and permitting managers from EPA, will work with permitting authorities to provide a smooth transition to GHG permitting and consistent GHG permitting guidance.
